apollo.dataadapter.das.simple
Class DASSequenceContentHandler  

java.lang.Object
  org.xml.sax.helpers.DefaultHandler
      apollo.dataadapter.das.simple.DASSequenceContentHandler

All Implemented Interfaces:

org.xml.sax.ContentHandler, org.xml.sax.DTDHandler, org.xml.sax.EntityResolver, org.xml.sax.ErrorHandler

---

public class DASSequenceContentHandler

extends org.xml.sax.helpers.DefaultHandler

I am the ContentHandler used when SimpleDASServer parses the result of a 'dna' call to a das data source (passing in dsn and segment).

I am DAS 1.0 compliant.

During the parse, I create a list, stored on myself, of the returned sequences. This list is retrieved by calling getSequences after the parse is complete

Description copied from class: org.xml.sax.helpers.DefaultHandler

Receive notification of the end of an element.

By default, do nothing. Application writers may override this method in a subclass to take specific actions at the end of each element (such as finalising a tree node or writing output to a file).
